Probability distribution: A probability distribution is the distribution of the probabilities for discrete individual events in a given experimental setup or situation. It is given by a probability function. While a uniform distribution is to be expected for a dice, the distribution of e.g. the expected body sizes of a human population will be concentrated around a mean value.
